Erebus is an anthology horror film inspired by the well-documented history of supernatural phenomenon in Rhode Island. Using Block Island's intimate setting as a backdrop, Erebus centers around the Gorham House, a mysterious old hotel with a torrid history of violent occult activity, as well as supernatural, and paranormal. Seeking to document the hotel for a new book, Samantha and Benny, journey to investigate the hotel, learning of its terrifying history along the way by relaying three horrifying tales of its previous owners. "Devil" - Robert Neville was the reclusive inheritor and owner of the Gorham House in the 1950s. Within the bowels of the hotel he harbors a grotesque secret, which unfortunately for him, just got out. "Exposure" - Frank Martin is a 1970s era forensic photographer who is commissioned by the historical society to take on the task of photographing all their properties, starting with the Gorham House.
